I think that is a call only you can make, because you have to deal with the consequences. If it were me, I would be concerned about the drugs impairing my judgment and perception. If I were prohibited from operating machinery, like a car, then I would probably elect not to carry during that period. Consider that, if it is known that you were carrying while taking a drug that impairs your ability to drive, it might be considered equivalent to carrying while intoxicated. Just a thought.
